Identification System for Power Plants Consistent use if a single uniform identification system which covers all applications involved in the planning, construction and operation of power plants is imperative. No other means en-ables universal communication between the vast number of parties involved in a project and per-forming hugely diverse tasks at different locations. One such system is the KKS Identification System for Power Plants KKS was developed by a study group founded in 1970 comprising planners, operators, independent experts and licensing authorities. It evolved from the Plant Identification Code (AKZ) and the owner's Component Code (BES). KKS structure and format are patterned after AKZ. Works on KKS has continued since then under the direction of the Technical Committee on the "Engineering Classification Systems" subordinate to the VGB Main Committee on "Thermal Power Plants". The following are currently members of this Technical Committee: BERLINER KRAFT- UND LICHT (BEWAG)-AG Brown, Boveri & Cie. AG Energieversorgung Schwaben AG ESCOM, Republic of South Africa Gesellschaft für Reaktorsicherheit Maschinenfabrik Augsburg-Nürnberg AG Rheinisch-Westfälisches Elektrizitätswerk AG Schnell-Brüter-Kernkraftwerksgesellschaft mbH Siemens AG, Groups E and KWU Steag AG VDEN, The Netherlands Vereinigte Elektrizitätswerke Westfalen AG Vereinigte Kesselwerke AG

KKS was published by the VGB-Verlag in 1978 (first edition) and 1983 (second, revised edition) in the form of a master volume containing application guidelines and keys, and it forms the basis for coding power plant systems and plant items. The response to the second edition has indicated that the KKS is being increasingly used in planning, construction and operation of power plants at home and abroad. Practical experience has shown that subdivision of the descriptive documents into KKS rules and KKS application commentaries

is more expedient. For this reason, the third edition (1988) is subdivided as follows: KKS Rules

Requirements and Tasks Today's power plant engineering and modern man/machine communication necessitate a common language for communication between all engineering disciplines such as civil engineer-ing, mechanical engineering, electrical engineer-ing and instrumentation and control. The demand for higher levels of safety and cost-effectiveness place increasingly stringent requirements on planning, construction and operation. Increasing unit power outputs and higher degrees of automation result in a pronounced increase in the overall quantity of data to be handled. A uniform coding system tailored to cater for all associated tasks and applications is conse-quently imperative for the planning and opera-tion of power plants.

The KKS Identification System for Power Plants fulfils these requirements. It

Provides a common language for all fields of application

Offers full coverage and ample reserves for advances in engineering and new technolo-gies

Can be combined with other coding systems

Is compatible with national (DIN) and inter-national (EC), ISO) standards

Is now in worldwide use.

The following requirements were considered during the development of KKS:

Uniform identification for all types of power plant and any connected processes

Sufficient capacity and detail for identifica-tion of all systems, components and structures

Sufficient capacity for extension to accommodate new technologies

Consistent identification for planning, licens-ing, construction, operation (control room), maintenance and decommissioning

Interdisciplinary applicability to mechanical, electrical, instrumentation and control and civil engineering coupled with identification according to process function, mounting location and topographic location

Quality assurance requirements

Requirements for the administration and documentation of technical documents

Type and Hierarchy of Identification KKS comprises three different types of code: Process-related identification

Process-related identification of sys-tems and items of equipment according to their functions in mechanical, civil, electrical and instrumentation and control engineering

Mounting location identification Identification of mounting locations of electrical and instrumentation and control equipment in mounting units (e.g. in cabinets, panels, consoles)

Topographic location identification Identification of topographic locations in structures, floors, rooms and fire areas.

The structure of the code blocks is the same for all three types of identification. The code is subdivided into breakdown levels and denotes progressively smaller entities from left to right. Mounting location and topographic location codes do not include the "component" breakdown level. DIN 40719, Part 2 uses the coding block "plant" for the purpose of process-related identification and the coding block "location" for the purpose of mounting location identification. DIN 40719 does not include the mounting location code in the form used by KKS. If necessary, the individual types of identification (in accordance with the standard) are distinguished by prefix symbols ("=" for plant,"+" for location). The DIN standard designates the code breakdown level as "section". The titles of KKS breakdown lev-els were established before the designations given in the above DIN standard were stipulated. Renam-ing was foregone in order to avoid having to make changes to KKS which was already in use at the time the DIN standard appeared. The adjacent diagram shows the content of the various types of identification.

Application of KKS This type of identification is used for mechanical,

civil, electrical and instrumentation and control engineering equipment units and components. Breakdown levels from different engineering dis-ciplines can be combined where necessary. Process-related identification is of prime concern for many applications. It permits, for example, the correlation of room and mounting space codes for electrical and instrumentation and control engi-neering systems or signals output by analog data signal conditioning equipment. This type of code also forms the basis for grouping instrumentation and control systems to form functional units.

Application of KKS

This type of identification is used for identifying the mounting locations of electrical and instru-mentation and control equipment and devices in consoles, panels, cabinets and sections of panels. Breakdown level 3 is not used in this application.

DIN 40719 provides for a "location" code block which is identical to that used in KKS for mount-ing locations but which is also used for coding topographic locations such as structures, floors and rooms. The complexity of power plants and the depth of identification which this entails, however, make it necessary for the process-related and mounting location codes to be combined to indicate topographic locations in an independent room code (described below).

In accordance with DIN the mounting location code is denoted by the "full stop" breakdown symbol written between breakdown levels 1 and 2. Information on structural items of hardware packaging systems (consoles, panels, sections of panels, cabinets) is written to the left of the full stop, and the mounting locations (tier, space) of devices and items to the right.

Structure and Contents of Breakdown Levels For reasons of clarity, memorization and unique-

ness, the individual breakdown levels are struc-tured alphanumerically with different formats.

Alpha characters are reserved for classification purposes, numeric characters for numbering; grouping is possible. No characters may be omit-ted on any breakdown level. The meanings of alpha characters are stipulated in the KKS Key. Mnemonic designations were avoided to facilitate international use.

It may be necessary to identify several units, non-unit-specific plants or plant extensions within one power plant in a manner that clearly denotes them as separate entities. Breakdown level 0 is pro-vided for this purpose. It is subject to agreement between all parties to this project. The use of an alphabetic symbol is recommended since the fol-lowing character is numeric. This breakdown level may be omitted if the identifier remains unique.

Prefix number: Character F0 is used for numbering similar sections of plants (e.g. identical heat gene-ration systems) in the total plant identified on breakdown level 0. Each prefix number applies only to that system or plant referred to by the following alpha characters and is not an alternative to the numbering entered in FN.


The alpha characters of this breakdown level subdivide the total plant into main groups, groups and subgroups, the numeric characters subdivide the entity classified by the final alpha character into sections, parallel trains, cabinets, floors, etc. Where assignable, the alpha characters including their interfaces, have been defined in the VGB key. Any unreserved letters in the function key must be supplemented on a project-specific basis.

Format and Contents of Breakdown Levels


The meaning of the alpha characters (A1A2 of this breakdown level varies the type of identifica-tion. In Process-related identification they denote

equipment units, instrument/control loops, analog data conditioning Mounting location identification they number

coordinates in structural items Topographic location identification they

denote rooms, fire areas, structure/room coordinates.

The additional alpha character (A3) is used in process-related identification to denote items such as pilot valves, twin thermometers, etc. and in mounting location identification to denote non-standard equipment mounting locations. The numeric characters of this breakdown level number the entities classified in A2 in all types of identification.


The alpha characters of this breakdown level classify mechanical, electrical and instrumenta-tion and control components. This permits identification of every individual power plant component e.g. pump, fan, motor, valve, ampli-fier, vessel. In addition, these alpha characters denote signals and their applications. The numeric characters of this breakdown level number the entities classified by the final alpha character and signals and their applications.

Main groups and prefix symbols for breakdown levels 2 and 3 The A1- und B1- characters of breakdown level 2 share the letters of the alphabet and special symbols. A distinction is, however, made be-tween main groups and the "prefix" for instru-mentation and control signal identification. These A1 coding letters are also standardized in DIN 40719, Part 2, Appendix C, Table C 2.

Further KKS Applications KKS as a master coding system and combination with other coding systems The formal/logical structure of KKS makes it suit-able for use as basis for coding in computer proc-essing. The identification levels plant/system/ equipment unit/component permit all forms of evaluation, e.g. with regard to mounting location, materials, systems.

KKS or portions of the KKS key can also be com-bined with other coding systems, such as the Documentation Key (DAS), Type key to permit correlations for specific tasks, Material Key for damage statistics.

Additional and special electrical and instrumentation and control engineering applications Identification of connections

Identification of signals

An additional identifier is required in electrical and instrumentation and control engineering for cod-ing electrical connections to devices, socket con-nectors, terminal blocks, etc. Connections are identified in accordance with DIN 40719, Part 2, using the prefix symbol ":" (colon) in conjunction with the code block "connection". This dedicated code block is used in conjunction with breakdown level 1, 2 or 3 as appropriate to the respective function concerned.

Breakdown level 3 is used to identify signals in lieu of components in order to permit coding of analog and binary signals in instrumentation and control signal conditioning and processing equip-ment. The coding letters X, Y and Z are used as "prefixes" in character B1 for this purpose. X is used to identify signals (origin), Z to identify com-bined signals (e.g. gated or calculated) and Y is used to identify signal application (destination). Character B2 is used to identify signal areas and signal application areas and character BN is used for numbering the entities classified by the char-acter B2. This identifier permits unique identification and tracing of all signals in circuitry documents.

20

Further KKS Applications

Further KKS Applications Identification of cables is also patterned after the basic KKS system. Cable identifiers consist of an alpha and a numeric element. The alpha element is that alpha element on breakdown level 1 of the two cable destinations nearer the beginning of the alphabet, and the numeric element numbers the cables. Grouping can be performed to sim-plify planning, e.g. power cables > 1 kV, ≤ 1 kV, control/instrumentation cables > 60 V, ≤ 60 V.

Identification of function

Process-related identification of plants, plant items and components is based on the respec-tive location in the power plant process, e.g. valve on the feedwater tank. This identifier fre-quently does not uniquely indicate function or functional task. A "functional group" always comprises a number of items of equipment be-longing to various systems with different KKS codes, e.g. feedwater pump system, piping sys-tem, tank, oil supply, cooling water.

In order to correlate the equipment units and items of such a "functional group", a "functional group code" can be used for the purposes of sorting and grouping.

"Functional group codes" are patterned after KKS. The alpha element of the dominant identi-fier is selected as the "functional group code". This application does, however, require the ad-dition of a suitable code (such as a "pseudo-prefix" Y to ensure that a software coding unit is concerned thus to rule out the possibility of confusion with process-related codes.

Several functional groups can be combined to form a functional complex such as in imple-mented in the TELEPERM® ME power plant process control system.

Example: cabling of final control element Explanation of characters for example CDB 4027

CDB: alpha characters of code nearer the beginning of the alphabet

4: cable grouping, e.g. according to application area 027: cable number

This form of code is used primarily for identify-ing documents.

Servicing of KKS is performed within the VGB Main Committee on "Thermal Power Plants" by the committee on "Engineering Classification Systems". The three subcommittees on "Mechanical and Civil Engineering", "Nuclear Engineering" and "Electrical and Instrumentation and Control Engineering" report to this technical committee. The results of these efforts are published in theKKS Manual Identification System for Power Plants Application Guidelines Function, Equipment Unit and Component Keys and in the KKS Application Commentaries. The information from the keys collated in this docu-ment comprises excerpts from the manual. The Manual and the KKS Application Guidelinescan be ordered from:

VGB-Kraftwerkstechnik GmbH - Verlag techn.-wissenschaftlicher Schriften - Klinkestraße 27-31 4300 Essen West Germany

The technical committe on "Engineering Classifi-cation Systems" will make the appropriate addi-tions and alterations to the guidelines and keys tc reflect future advances in power plant engineer-ing. Siemens is a member of this committee. Que-ries may be directed to
